Hyip promoters-forums fake posters?What experiment was made by ECJ-freelancer?

I personally always trusted users on forums like moneymakergroup.com or other very big forums when they rated a hyip and posted payment proofs. It looked a little strange that no one of them posted actual screenshots of payments like pictures, they just copy-pasted the information. I realized an experiment on last year's April to see how much do people invest in a ordinary scam that looks like one. This year I created a very professional website hyip and wanted to see how much money will people invest on it if I don't promote the hyip at all. The sum invested was just 70$, fact that shows that people have lost trust in hyips, even though they look professional. But the greatest part just comes.

After the website was launched, the second day there were about 15 e-mails in my contact e-mail address. Some of them told me that my hyip was posted on several forums, some with offers from hyip monitoring programs, to which I had to pay, of course, but 5 of them were very important. They came from people or group of people which asked me money, lots of money to post positive things about my website on moneymakergroup.com. They were all old users on the forum that had lots of posts and people trust them. One of them even asked me money to post fake payment proofs on the forum! The sums varied from 100$ to even 900$, depending on the number of posts, the number of payment proofs and the number of individual users to post about my hyip. I was also threatened that If I don't use their services, they will post negative things about it, and so did them. So since that day I don't trust forums any more. This looks to me like a organized crime group, that take money to post fake things. What do you think?
